EPDM Roof systems
Durability, design versatility and installation ease are among the many reasons EPDM is the most popular material for both new and re-roof and low- slope roofing applications. EPDM membranes may be installed in a full range of system applications.
The earliest predominant design was the ballasted roof, in which this rubber-like membrane is loosely laid over the substrate [usually loose laid insulation). The single ply membrane is then covered with a layer of ballast, stone or pavers, which serve as the anchoring method keeping the membrane in place when exposed to wind uplift forces. EPDM membranes may also be fully adhered to rigid insulation board or an appropriate structural deck.
This system eliminates the weight of the ballast and leaves the membrane exposed, thus offering many opportunities for aesthetic appeal through the use of specially colored membranes and coatings or just the smooth, clean appearance of an adhered black membrane. It has a proven track record and has been installed for many years by MAG Roofing. EPDM can endure almost anything nature can throw at it – from a hot sun to a cold winter – and still hold up very well. It’s properties of resilience, tensile strength, elongation, resistance to ozone, ultraviolet light and ponding make it an excellent strong roofing material.
